Abstract
A system (20) for quality assurance of a magnetic resonance (MR) imaging device (23) used in magnetic resonance based radiation therapy planning includes a phantom (10) weighing less than 18.2 kg (40 lbs.). The phantom includes a three dimensional spatial distribution of MR and CT imagable elements (12) located in an MR and CT inert foam support (14), and an MR and CT inert external support structure (16) which surrounds and hermetically seals the foam support. The spatial distribution is sized to completely fill an imaging volume of the magnetic resonance imaging device.
